How's this for an educational product idea: Use AI to read a student's essay, then produce exam questions based on the content. This test would be delivered orally (with accommodation for disabilities that might impact their ability to complete the task, of course). The student should ace the test if they understood the subject well enough to ace an essay on it. They should know the answers very well, since the questions are specific to what they've apparently written. The mark they get on this test would be the research part of the mark they receive for the essay. Then it is just grammar, organization, etc. thereafter.
